"1.I am having lots of trouble making a surface using
BRepOffsetAPI_MakePipeShell. It crashes 50% of the time and even a try/catch
block will not catch it. I have attached a picture of a typical X section wires
and the spine that I would use (note that the X section wire can be make of 3-4
edges, not always a single edge). I am not using any auxiliary spines or any
other options. Simply initialize with the spine and then add the 2 X sections
that are at the two ends of the spine which are already orthogonal to the spine.
2. BRepOffsetAPI_MakePipeShell exitPipeShell2(exitTransSpineWires[1]);
exitPipeShell2.Add(exitTranSectWires[1],Standard_False,Standard_False) ;
exitPipeShell2.Add(exitTranSectWires[2],Standard_False,Standard_False) ;

exitPipeShell2.Build(); <- this line crashes the code.
If I do not add the 2nd profile it does not crash."
